Unauthenticated Cross Site Scripting (XSS) in ReviewX <= 2.3.10 versions.

AnalysisAI

Reflected/stored Cross-Site Scripting in the ReviewX WordPress plugin (versions 2.3.10 and earlier) allows unauthenticated remote attackers to inject arbitrary JavaScript that executes in a victim's browser when they interact with a crafted request or page. The scope-changed CVSS 3.1 score of 7.1 (PR:N/UI:R) reflects that no authentication is required but a victim must be lured into triggering the payload. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, so this is a disclosed-but-not-yet-actively-exploited plugin flaw reported by Patchstack.

Technical ContextAI

ReviewX is a WordPress plugin providing multi-criteria product/business review functionality (commonly paired with WooCommerce). The affected component is identified only by the wildcard CPE cpe:2.3:a:reviewx:reviewx:*:*:*:*:*:*:*:* covering all versions up to 2.3.10. The root cause is CWE-79 (Improper Neutralization of Input During Web Page Generation), meaning user-supplied input - likely a review field or request parameter reachable without authentication - is rendered back into an HTML/JS context without proper output encoding or sanitization, letting attacker-controlled markup execute as script in the browser DOM.

RemediationAI

Update the ReviewX plugin to a version later than 2.3.10 as published by the vendor; the provided data does not include an exact fixed version number, so consult the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/reviewx/vulnerability/wordpress-reviewx-plugin-2-3-10-cross-site-scripting-xss-vulnerability?_s_id=cve) and the WordPress plugin repository changelog to confirm the specific patched release before deploying. If an immediate update is not possible, deploy a Web Application Firewall (such as Patchstack's own virtual patch or WordPress security plugins) with rules to filter XSS payloads targeting ReviewX endpoints, and restrict or disable public/unauthenticated review submission if the deployment allows it - noting this trade-off removes legitimate visitor review functionality. Adding a restrictive Content-Security-Policy that disallows inline script can also blunt payload execution, at the cost of breaking any legitimate inline scripts on affected pages.
